Hello, I have had problems with my gcc compiler when i compile C language codes. I've only begun to program C language, so it's the first time i program with C. I tested to compile my C code on my mac but it got errors. So i went to check if the code can compile on other devices, like my Raspberry Pi 3 Model B. And guess what? It worked without any problems! And it was the same code when i compiled it on my Mac... So is there any bugs or so on the gcc compiler on mac? Or maybe does MacOS BigSur have removed some important features to gcc to work properly? Any answers or questions are welcome!
[Here's the message i get when i compile.]
